It is to be understood that changes may he made in the construction and in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims. 7

What I claim is 1. In a tractor attachment of the kind described, a pair of planters adapted to be arranged at opposite sides of a tractor and eachhaving a forwardly extending tongue, a channeledcross bar suitably mounted forwardly upon the tractor and receiving in its channel the tongues, coupling pins engaged with the cross bar and tongues for adwstably connecting the same, feeding coupling common to the feeding means and connected therewith of both planters for operation in unison, driven connections between the coupling and a power wheel of the tractor, and manually operable means for the respective planters to independently adjust the same relative to a ground surface.

2. In a tractor attachment of the kind described, a pair of planters adapted to be arranged at opposite sides of a tractor and each having aforwardly extending tongue, a channeled cross bar suitably mounted forwardly upon the tractor and receiving'in its channel the tongues, coupling pins engaged with the cross bar and tongues for adjustably connecting the same, feeding means in each planter, a coupling common to the feeding means and connected therewith of both plant'- ers for operation in unison, driven connections between the coupling and a power wheel of the tractor, manually operable means for the respective planters to independently adjust the same relative to a ground surface, said feeding means each including a shaft,

said shafts being arranged in opposed alignment with each other, said coupling being in the form of a tube telescopically engaged over the shafts and adjustably secured thereto.

In testimony whereof I afix my signature.
